无权处分制度的设定与物权变动模式、善意取得等制度紧密相关,所以无权处分合同的效力也就成为了一个重要的课题。通过就我国无权处分合同效力的不同学说进行一定的分析和探讨。希望以此能对无权处分合同的效力有一个更加准确的认识。 The establishment of the system of non-punitive power is closely related to the system of change in real rights and the acquisition of goodwill. Therefore, the effectiveness of not having the right to dispose of a contract becomes an important issue. Through some analysis and discussion on the different theories that our country has no right to dispose of the contract. Hoping to have a more accurate understanding of the validity of the power to dispose of the contract.
